30/19: Difference between revisions

30/19, the small undevicesimal minor sixth is a 19-limit interval, 790.8 cents in size. In the Functional Just System and Helmholtz-Ellis notation, it is an augmented fifth, obtained by subtracting 81/80 and 513/512 from the Pythagorean augmented fifth, but it may be called the Eratosthenes' minor sixth as it is flatter than the Pythagorean minor sixth by the password aka Eratosthenes' comma (1216/1215), an unnoticeable comma of about 1.4243 cents.
